Hello, Would anyone know how to rate Morpheus and IRC etc as low priority traffic and capped to 128k on a Cisco 2501 with IOS 11.1?

A further addition to the interesting debate we have been having on Internet 2/broadband. OT perhaps, and relating to the US/Canadian scene, but fascinating.

Remember that in Wn we INSIST that a customer have a router at the edge. Its just that we make them buy it. THats because when we started (with $85K) routers were expensive and we avoided that outlay..

RE: Traffic Shaping

Sahil, If ICQ traffic uses fixed well known IP address and/or sockets then you can cap bandwidth with the "traffic-shape" IOS interface command. I don't know if this is the case or not. For example, here's how we cap SMTP traffic at 128K. First setup an extended access-list defining the IP addresses/sockets you want to cap. ! SMTP mail no access-list 125 access-list 125 permit tcp any any eq smtp access-list 125 permit tcp any eq smtp any The apply it to your interfaces - interface serial0 traffic-shape group 125 128000 interface ethernet0 traffic-shape group 125 128000 This will cap all SMTP at 128K in & out. regards Denis Gordon Network Administrator Information Systems Technical Support Dunedin City Council 50 The Octagon, PO Box 5045, Dunedin, New Zealand Ph: +64-3-474 3566 Fax: +64-3-474 3503 Mobile: 025 845 583 Email: denis(a)dcc.govt.nz WWW: http://www.CityOfDunedin.com/ -----Original Message----- From: Dean Pemberton [mailto:dean(a)flatnet.gen.nz] Sent: Wednesday, 27 February 2002 10:24am To: Sahil Gupta - NET4U Cc: nznog(a)list.waikato.ac.nz Subject: Re: Traffic Shaping I didn't think a 2501 passed packets any faster than that anyway?

I don't know what the case is with Jetstart, etc, as I've never used them (at least in a context where I was paying the bill). The "Paradise.Net model" I mentioned earlier charges 1/10th of the International charge for "local" (national, ie in New Zealand) traffic. This seems to work well for TSNZ, and it works well for me (as an end customer). Most other traffic-based pricing plans I've had over the last 10 years or so have had similar rules (including the ones that I implemented the software for way back when): cheaper rates for more local traffic. If Jetstart doesn't do that (ie charges national and international traffic at the same (high) rate), then yes, I agree, it's discouraging local use, and it's bad. International bandwidth is lots more expensive than national bandwidth (all that ocean all around) to the provider, so in a pass-the-costs-on model it should be more expensive to the consumer too. >Bandwidth has dropped in cost, but we download more, and faster, nowadays. I could easily get through "as much bandwidth as I can afford" way back then as I could now, if I tried. By no means is it perfect now. And yes, the charges in New Zealand are probably higher than charges overseas by pure exchange rates or whatever. But quite a number of providers overseas (eg, the US) appear to have been going out of business which is, umm, inconvenient for their customers, suggesting they're not entirely profitable charges there. Oh, and there's all that expensive-to-put-bandwidth-over ocean between New Zealand and pretty much anywhere else. That sort of adds to the cost, meaning direct comparisions aren't entirely appropriate.

Simon's SCC question

http://www.southerncrosscables.com/layup.htm -- not sure if it's accurate/up-to-date, but the roll-overs say that there are three fibre pairs, each with sixteen wavelengths with a 10Gbps bit rate, going to Australia and to Hawaii. 3*16*10=480Gbps, presumably. Wonder how much of this is in use though? -- Juha Take off every sig! - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
